Definitions

  • the present invention relates to a seal arrangement (i.e., assembly) and to a fluid valve or fluid control valve having such a seal.
  • a fluid valve or fluid control valve is to be understood here as meaning in particular a cooling-water valve or cooling-water control valve, in particular for use in a vehicle.
  • a vehicle is to be understood here as meaning any type of vehicle which has to be supplied with a liquid and/or gaseous fuel for operation, but in particular passenger motor vehicles and/or utility vehicles.
  • the vehicle may also be a partially electric or fully electric vehicle, but in particular passenger motor vehicles and/or utility vehicles.
  • Seals as such can have different roles. They can, for example, serve to prevent or at least to limit undesired fluid losses.
  • a fluid can be understood here as meaning a liquid and/or gaseous medium.
  • An object of the present invention is to provide a seal arrangement for use in a fluid valve, in particular in the form of a cooling-water valve, in particular for use in a vehicle, wherein the intention is for the seal arrangement to meet the highest requirements for long-term leak-tightness under known large temperature variations of a combustion engine periphery and/or an electric motor periphery.
  • the seal arrangement should be inexpensive to produce, and should make possible force- and friction-optimized operation of the fluid valve.
  • a seal arrangement for use in a fluid valve that includes:
  • integrally formed on the proposed valve body sectionally is at least one elevation from the valve body lateral surface for activating the seal in a closed position of the fluid valve.
  • the elevation is to be understood here as meaning a contour or raised contour of the valve body that protrudes from the valve body lateral surface, or is raised therefrom, in order to interact, in a manner dependent on a valve body position, with the assigned seal.
  • a closed position of the valve body this simultaneously being a closed position of the fluid valve—the contour presses against a contact point, having linear and/or areal sealing action, of the seal.
  • the seal which as such is elastically deformable owing to the interaction with the valve body, is compressed and braced.
  • This is associated with an activation of the seal, which as such applies its complete sealing action for the first time through this elastic deformation.
  • the seal undergoes relief of tension since outside this closed position it does not interact with the elevated contour, because the sealing action is not required outside this closed position.
  • the proposed elevation or elevated contour of the valve body lateral surface thus makes possible force- and friction-optimized operation of the fluid valve.
  • This in turn is associated with relatively low current or energy consumption on the part of an actuator for controlling the fluid valve, and this in turn counteracts self-heating of the actuator and is consequently favorable in terms of its service life.
  • the proposed elevation or elevated contour facilitates the fitting of a fluid valve having the above-described seal arrangement.
  • the surface of the contour is, together with its transitions to that portion of the valve body having the contour, advantageously configured here to be smooth to such an extent that the seals are not damaged when interacting with the contour.
  • the elevation may advantageously be integrally formed in a closed encircling manner on the valve body lateral surface. This brings about uniformly elastic deformation of the seal along the circumferential extent thereof, that is to say uniform activation of the seal along the circumferential extent thereof.
  • That portion of the valve body having the elevation may be of spherical form. This is associated with particularly good sealing action of the seal arrangement.
  • the valve body may however also be of cylindrical or substantially cylindrical form or even have a different shaping, for example a sectionally spherical and/or cylindrical shaping. Another differently convex curvature of that portion of the valve body having the elevation is in principle also conceivable.
  • a face side, facing the valve body, or a face-side end, facing the valve body, of the seal may be set at an angle or inclined with respect to a longitudinal direction of the seal in a manner corresponding to the shaping of the valve body.
  • the face side or the face-side end may include an angle of approximately 45° to 75° with the longitudinal direction. This too is favorable for the sealing action of the seal arrangement.
  • a fluid valve having a seal arrangement of the above-described type for sealing off at least one connection region of the fluid valve, in particular in the form of a multi-way fluid valve—which can function as a mixing valve and/or distributor valve.
  • a fluid valve may however in principle also be understood as meaning a switching valve, shut-off valve and the like.
  • a fluid valve of this type as a cooling-water valve, in particular of a vehicle, is also proposed.
  • the cooling-water valve may have the function of a mixing valve, distributor valve, switching valve, shut-off valve and/or the like.
  • FIG. 1 shows an embodiment of a proposed seal arrangement in a perspective view
  • FIG. 2 shows the proposed valve body, shown in FIG. 1 , of the seal arrangement in a perspective view
  • FIG. 3 shows a multi-way fluid valve in a sectional illustration with the seal arrangement shown in FIG. 1 ;
  • FIG. 4 shows an enlarged detail from FIG. 3 .
  • FIG. 1 illustrates a seal arrangement (assembly) 2 for use in a cooling-water valve or cooling-water control valve—or also referred to as cooling-water regulating valve—of a vehicle.
  • the seal arrangement 2 comprises an actuatable valve body 4 , which is formed from a plastic, for example by injection molding, and a total of two or three seals 6 .
  • the valve body 4 may be formed here, for example, from a PA66, PPA or PPS plastic.
  • portion 5 of the valve body 4 against which the seals 6 bear is advantageously of spherical form.
  • the portion 5 may be of cylindrical and/or spherical form.
  • the convex curvature of the portion 5 may also deviate from a classical spherical shape.
  • FIG. 2 illustrates a closed encircling elevation or raised contour 8 , which is integrally formed on the valve body portion 5 sectionally and which, as such, with the shape of a circular ring and in a manner corresponding to the in each case assignable, circular ring-shaped seals 6 , protrudes from the lateral surface of the valve body portion 5 or is raised from said lateral surface.
  • the valve body 4 is, for example, formed in one piece with a shaft 12 which is integrally formed on the valve body portion 5 .
  • the shaft 12 bears a multi-spline profile via which the valve body 4 is actuatable in a manner electromotively pivotable in at least one direction, but preferably in two directions, that is to say clockwise and/or counterclockwise, by an actuator into which the shaft 12 projects.
  • a passage 10 which is formed in the valve body portion 5 and through which cooling water flows, can also be seen.
  • FIG. 3 illustrates by way of example a multi-way cooling-water valve 14 having a total of three connections 16 , 18 , 20 , which need to be opened or closed and sealed according to requirement.
  • the valve body 4 with respect to the connection 18 , is visually depicted in a closed position, in which the connection 18 is closed and completely sealed off by the valve body portion 5 .
  • the cooling water can flow through the open connections 16 , 20 and via the passage 10 .
  • the third (non-illustrated) seal 6 can also be dispensed with in this exemplary embodiment.
  • FIG. 3 illustrates by way of example a multi-way cooling-water valve 14 having a total of three connections 16 , 18 , 20 , which need to be opened or closed and sealed according to requirement.
  • the valve body 4 with respect to the connection 18 , is visually depicted in a closed position, in which the connection 18 is closed and completely sealed off by the valve body portion 5 .
  • the cooling water can flow through the open connections 16 , 20 and via the
  • valve body portion 5 operatively connected, via the elevation 8 thereof, to the assigned seal 6 .
  • this operative connection does not exist because the sealing action of the in each case assigned seals 6 is not required in this position of the valve body 5 .
  • the interaction between the elevation 8 and a face side, facing the valve body portion 5 , of the seal 6 can be seen in particular in FIG. 4 .
  • the seal 6 is elastically deformed by the valve body portion 5 .
  • the seal 6 is, for example, formed in one piece and comprises an elastically deformable plastic base part, for example composed of an elastomer, for example of EPDM (EPDM standing here for ethylene propylene diene monomer), on the valve body-side, first face side of which for example a thin hard plastic layer is vulcanized.
  • This hard plastic layer which functions as a hard sealing element, may be manufactured, for example, from PTFE (PTFE standing here for polytetrafluoroethylene) and/or the like.
  • the valve body-side face side of the seal 6 moreover advantageously comprises a circular ring-shaped closed encircling bead which interacts with the elevation 8 with static and linear and/or areal sealing action.
  • the thin hard plastic layer is shaped in a manner complementary to the plastic base part, wherein the plastic base part extends into the hard plastic layer and in the process forms the bead.
  • the opposite, second face side of the seal 6 which may likewise be provided with a bead, bears with dynamic and linear and/or areal sealing action against a valve housing of the fluid valve 14 .
  • the seal 6 furthermore advantageously comprises a support ring composed of plastic or metal, which, relative to the passage opening of the seal 6 , bears on the inner side or internally against the plastic base part and makes possible a stable installation of the seal 6 into the valve housing.
  • the seal arrangement 2 illustrated by FIGS. 1, 3 and 4 cannot be reduced to the seal 6 described. Rather, this seal 6 described is to be understood merely as an example, because the valve body 4 , 5 proposed in the context of the present disclosure is also able to be combined with other seal designs, which as such are advantageously able to be elastically deformed, and thus activated, by the valve body 4 , 5 .
  • the elevation or raised contour 8 of the valve body portion 5 acts like a step which needs to be overcome when one of the connections 16 , 18 , 20 is closed and sealed.
  • the contour 8 is pressed against a contact point, having linear and/or areal sealing action, of the assigned seal 6 , whereby the seal 6 is elastically deformed and in the process compressed and braced. This in turn is associated with an activation of the seal, which as such applies its complete sealing action for the first time through this elastic deformation.
  • the seal 6 undergoes relief of tension, since it is not operatively connected to the valve body 5 , because then the sealing action is not required.
  • the elevation or contour 8 is expediently designed to be smooth or smooth and slidable to such an extent that it cannot damage the in each case assignable seals 6 when interacting therewith.
  • the proposed valve body 4 , 5 thus makes possible force- and friction-optimized operation of the fluid valve 14 .
  • This in turn is associated with relatively low current or energy consumption on the part of the aforementioned actuator unit for controlling the fluid valve, and this in turn counteracts self-heating of the actuator unit and is consequently favorable in terms of its service life.
